Product: HealthPatch is an FDA approved wearable, disposable, biometric sensor patch that sits on user’s upper torso area for 3-7 days and monitors all of user’s vital signs including EKG waveform, heart rate, caloric burn, activity, and posture. Physicians or nurses who oversee the data will be notified if there is a change in the condition of the user.
​
​By the time I joined VitalConnect, the founding team had a proof of concept for the patch idea but we didn't know how the patch would look like, what the dimensions and materials would be, how user should assemble the patch, how user should put the patch on the body, where user should wear the patch, how many days the adhesive can last, etc. My design had to optimize 3 opposing aspects of the product:
​
-
Wear comfort
-
Adhesive durability
-
EKG signal quality
​
​
The challenge with this design was that these 3 factors moved in different directions and were not aligned.
​
Getting to the point of final design required designing lots and lots of use case scenarios, tons of user testing, a lot of mechanical testing, environmental testing, iterative 3D modeling, prototyping, making assumptions and re-evaluating after user testing, etc. In addition to these roles I also had to document everything for FDA submission and had to design studies for clinical trials. I was also in charge of choosing and managing some of the local and international vendors for mass production.

I love it when I get to put on multiple hats in a project. I can see the big picture well and I get to work with multiple departments and learn from them.
